The mythological action film, due in March, will be shooting additional scenes and bulking up its budget before its release date, the "Avatar" actor told the newspaper.

"We're going to be going back and shooting more scenes for it, they cut loose with some money so we can add to it," Sam said, noting that the last-minute shooting would be on a tight deadline.

"We're going to be shooting more scenes in January, so we're going to be right up against it — the movie comes out in March," he said.

But the star said the decisions were based in Warner Bros.' confidence in the remake of the 1981 film – not to fix flubbed scenes.

"There were some creaky parts but they are the parts that we knew were creaky and that we knew were going to be creaky going into it," he said. "The studio is also letting us add some gods and scenes. And they're talking about making the movie a 3D film."

The Australian actor stars alongside Liam Neeson and Ralph Fiennes in "Clash," with "The Incredible Hulk" helmer Louis Leterrier directing. Whatever its new budget, it's doubtful that it touches the cost of Sam's current film, "Avatar," which a New York Times report estimated at $500 million in November.

"Avatar" performed strongly in its first day of release, earning an estimated $27 million domestically.
